Front fork refurb/rebuild: Situation & options.

[Peasy]

Just following on from this as I still exploring all avenues....

Spoke to Yamaha Tech UK and they are saying completely the opposite to Tyres4bikes, Brooke,m Maxton, ketech, etc etc.. They have said all I need to do is have the right weight oil in there and the steps would be -

1. Drain the oil out of forks and leave to drain for a few hours.
2. Flush the forks with cheap 5w oil, and again leave to drain.
3. Then place correct amount of Kayaba 01 (from what I have found online this is 5w oil)

Then set the forks back to std setting (if not already) and work work from there.

Yamaha and Tyres4bikes have never heard of the cartridge tube wear, as per Maxton's statement. And as these replacement Stainless Steel tubes cost £100 plus vat per pair I am leaning away from going with them (Ktech was out of the window ages ago due to the new ludicrous price PDQ quoting @£750 fitted).

So now I am at the stage where I am strongly considering Tyres4bikes, as for £180 they will

• dissemble and clean all the internals.
• change the oil and dust seals.
• replace the fork oil with 7.5w.
• return postage.

@Peasy, can you give me a break down of what your bike was like before and after please?

Sorry for late reply mate, been away. To be honest I'd not had my fazer long when I did the r6 rear so just did the front anyway so not much to compare to from before really. Sorry. It's almost 2 years and after refitting and a quick setup I've not touched them at all.


These were my forks stripped down just to see what's all there...

@Peasy, took mine apart today. It looks like previous owners have been at the forks and internals as there are marks, burs and scratches everwhere.

But back on topic, I took some pics of 2 things that troubling me - the damper tube and the preload adjusters on the fork tops -

• There is some(I can just feel and see it) sideways (lateral play) between the damping piston and damping tube - is this normal?
• The preload adjusters only come out to 4.5 lines, I'm guessing this wont be an issue if I am heavy enough etc.

And like Falcon, I found some swarf inside both damping tubes, as well as the usual gunge.

Just a small question on this.


Has anyone use 3rd party fork bushes on this bike? or is it advisable to use genuine only..? I ask because Wemoto are less than half the price of genuine etc.


ta.

I bought all my bits from K-Tech so non OEM, I'd probably go OEM seals if you can but I can't see pattern bushes being an issue.

Any thoughts on the above..?
